I'm thinking about getting a TC4, the "club racer" version for racing, and was wondering how tough this car is? Are the stock plastic suspension mounts strong enough for normal racing or do I need to upgrade to the aluminum ones?

i raced mine today! handles great! the only durability issue i have is the front driveshafts, they certainly need to be something stronger than plastic. however other than that it took a few good shots today and came back kicking!

something that i did that really helped rear grip was trimmed the rear chassis braces off, gave the back end some more flex and the car was pretty dialed on my track!

when using a spool you really need steel driveshafts like the asc-2402, the plastic ones are fine if you run a diff.

Thanks. How well do the composite outdrives hold up? Do they need to be upgraded to steel?

oh man... got me some upgrades coming! im going to have this car dialed. those tc6s wont know what hit them.

as for the outdrives, mine dont seem to worn, but they probably only have 15-20 packs on the car so far. they are on my short list to upgrade though.

i mostly want to get a solid suspension set-up on the car and take care of the durability issues with the front driveshafts (i have some losi LCAs coming.)

anyone one have gearing recomendations for 17.5?

Default LOSA 3344 & C-Hubs

Speaking of Losa #3344, I bought a set, built it, and never put it on my TC4 since I decided to turn it into a drift car. I have the LOSA 3344 JRX-S along with several sets of the LOSA C-Hubs that are still BNIP. Anyone want them?

something like that. it was simple and it made the rear end of the car much more predictable.

Before removing chassis braces which may lead to stripped gears and bent shafts I would first work on the suspension to properly set up the car.
I see you have blue springs in the rear, have you tried silver or green ?? both will increase rear traction. There are so many adjustments on the TC4 to add or remove traction I dont understand why you would start by removing chassis braces

i didnt have springs to change at the track yesterday. i dont see any reason it should change the gear mesh... i even checked that at the track, it doesnt change.

we'll see how it holds up.

Springs and roll center on the arms and upper links are good places to start, I usally run green or silver springs in the rear with #3 shims under both rear arm mounts and 3mm spacers under the upper link.

How well could a TC4 do against the newer chassis? I'm thinking of getting a cheap TC4 (plastic tub version) to race in 17.5 blinky class. I don't really want to spend $400 or more on a current chassis because I really don't know how much racing I'll be doing. I'm assuming since 17.5 isn't exactly a lot of power, even an old chassis like the TC4 should do ok. What do you think?

this is my plan to a t. ill let you know how it works out... from the surface of it yesterday my buddys tc6 was running identical lap times. we were on similar tires, and had similar motor/esc set-ups.

If you don't have a solid spool for your TC4, I would suggest getting one if running it in 17.5. It will help the car get out of the corner if you are running on a high bite surface. The TC4 club racer comes with a solid front spool.

The only major tuning advantage that newer cars have is gear diffs - since they can change oil as a tuning option. The only AE options for the TC4 are ball diff, solid spool, and one-way. However, there are DIY options to create a slipper spool out of a stock TC4 ball diff with a few inexpensive parts.

so raising the inner camber links on the rear=more rear traction?
